Discounts may be offered for reduced service levels. I have no direct experience with the earlier models. Early and mid production models used the traditional numbering scheme A nnnnn.
Ratings and Reviews Write a review. But, then one would also need 3400q confirm the stability of the input ACV amplitude as well as the thermocouple-heater pair. Please correct the issue indicated and resubmit or contact us via email or toll free at and we will be happy to assist you with this request. The lowest-priced item that has been used or worn previously.
This item doesn’t belong on this page. Another approach might be to do the test with two or more A and move the A6 board with the socket between the units in separate test runs over temperature. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. The fear of sockets in uV circuits is in our opinion over-rated.

Showing Results for Keysight Technologies (Agilent HP) 3400A
The manuals for the hp A are widely available from the Agilent website and other manual down load sites, so we have not re-scanned or re-posted it here. It might not be such an easy project!
Jim’s absence will be a huge loss to the Analog design community. However, as noted by Horowitz 4300a Hill , for Johnson noise measurements, a small correction factor does the job. Work both new long rectangles of foam into the slots and then work the board back into the new foam. Replacing the A2 board foam: Additional Info Please provide any additional information which could help us determine whether we can meet your requirements for this offer.
Since then, we have been investigating low cost solutions for low level AC measurements.
With the power off, the meter needle should be on “0”. Thank you for allowing us the opportunity to assist with your test equipment needs. Use at your own risk.

A RMS VOLTMETER [Obsolete] | Keysight (formerly Agilent’s Electronic Measurement)
Understanding and selecting rms voltmetersFailing to verify ac-voltmeter accuracy before conducting rms-noise measurements may cause highly misleading results, Jim Williams and Todd Owen, Linear Technology Corp, EDN, May 11, One caution that should be observed is that the thermocoupling circuitry can be damaged by excessive overloads more easily than conventional meters so always start the meter at a higher voltage setting and then scale down to the range to be measured.
Here, I wanted the option to try a few different versions of this same part, so the socket. We would also greatly appreciate it if you could provide us with this error code: Also in a classic approach, the voltage signals from the two thermocouples are added with one of the two having a “reverse” polarity connection, so that when they are at the same temperature, their voltages cancel to near zero.
If you are looking for a late model A series from and some later years, the only way to be sure might be to see the prefix in a picture of the rear panel or to ask the seller.
HP A RMS Voltmeter
Additional Info Please let us know any information that will help us fill your requirement such as urgency, quantity needed, etc. Equipment Offer Sent Your offer has been sent to our sales department for review. Here is a technical data sheet for the version of the hp A PDF. Note the older style hp front panel logo, the red lensed power light, the silver power toggle switch and the older oval style line cord.
Mouse move on Image to zoom. A “balancing” amplifier applies whatever DC voltage is needed to a second heating element attached to a second thermocouple to match the temperature of the first heating element. It shows some wear as pictured. Standard accessories supplied by the original manufacturer No manuals or accessories required Other specify Will you accept an instrument with minor cosmetic and physical flaws if it operates properly?
That is why as long as it reads correctly at both points and in-betweenwhere it falls between the zero mark and the first mark with no signal input, is of no consequence. The HP A also offers a crest factor of Cut new foam pieces from a high quality open soft packing foam typically a dark gray color. Please let us know which of these you would be willing to consider for the price discount.
Probably all of the foam inserts are decomposing by now. As well documented at other sites, there has been an evolution of the HP A series meters from their introduction inthrough the late s ending with the B.
